Italy to start fingerprinting migrants at sea

Italy is to introduce the fingerprinting of migrants crossing the Mediterranean as soon as they are picked up by rescue boats, officials say.

The move could help to reduce mounting tensions between Italy and its EU partners over the large numbers of migrants who arrive in Italy but are not registered here and then travel on to northern Europe.

If they are not registered in Italy, neighbouring countries like Austria and France and popular destination states like Germany and Sweden do not have the option of sending them back to Italy.

In theory they should be able to do this under the EU's Dublin convention rules governing asylum claims.
